Mr. Liang from Zhongshan has a MID electroplating production line, specializing in the processing and production of various mobile phone antennas with chemical copper and nickel plating. Recently, Mr. Liang's antenna workpiece has been prone to over plating during electroless nickel plating after copper deposition. Mr. Liang checked the process parameters of the chemical nickel solution and palladium activator and found no problems, so he wanted to search online for the answer.
On this day, Mr. Liang found Bigley Technology through online search and inquired about the characteristics of chemical nickel solution and palladium activator, as well as the reason for the workpiece overflow plating. After a detailed understanding of Mr. Liang's production situation, engineers from Bigley explained to him that this was mainly due to the poor stability and strong activity of palladium activators. Palladium was also deposited on the surface of the workpiece where nickel did not need to be deposited, resulting in the phenomenon of over plating on the workpiece.
The new research and development technology of Bigel is used as the palladium activator, and the high-purity Palladium(II) chloride from Switzerland is used as the raw material. The palladium activator has good stability in the production process. As long as the concentration of the palladium activator and the passivation time are well controlled, the workpiece will not have the phenomenon of plating overflow. The operation is simple, and the defective rate of the workpiece can be effectively simplified. After considering, Mr. Liang decided to purchase 1 kilogram of palladium activator for comparison.
Under the guidance of the engineer, Mr. Liang used this palladium activator and, following the same production process, found that the previously overflowed workpiece is no longer available. Moreover, the stability of this palladium activator is good, and the service life of the working solution has been extended by more than twice, which can effectively reduce production costs. So, Mr. Liang prepared to use Bigley, a palladium activator, for a long time and signed a cooperation agreement with Bigley.
So, when our mobile phone antenna is plated with chemical nickel after copper deposition, it is found that the coating always overflows. It is recommended to try Bigley's palladium activator to reduce defect rates and save production costs.
